Abstract
We show how optimization of the Nordstrom and Mumford-Shah functionals can be used to develop a type of curve-evolution that is able to pres erve salient features of closed curves while simultaneously suppressin g noise and irrelevant details. The idea is to characterize a curve by means of its angle-function and apply the appropriate dynamics to thi s representation. Upon convergence, the resulting form of the contour is reconstructed from the representation.
